B e itknown that I, OHARLns W.. LINDSAY, a; c1t1zen of the United States, residin at Houston, in the county of Harris and tater ofTexas, have invented certain new and useful Improvementin Single-TriggerMechanis'mfor Double-Barrel Guns, of which the following is a specification. j r

The object of the invention is to provide a single trigger mechanism whereby both successively and in the order desired. t 1

Another object. of the invention is to pro vide means for shifting the mechanism and thus changing the order in which the barrels A; further feature resides in the provision bound of the gun succeedingthe recoil after It is also the object of the nvention to provide a single trigger mechanism which is constructed with .a minimum number of partsso that it may be easily andcheaply 1 mechanism of the ordinary double barrel Withthe above and other-ob ects 1n view, the invention has particular relation to oer tion and arrangement of parts, an example of which isgiven in this specificationiand illustrated in the accompanying draw ngs terior of the lock of a gun. 1

the usual double barrel gun in the sides of which are pivoted the hammer controlling sears 2,-2, provide'dattheir rear ends with corresponding inwardly turned projections 3.3,- through which the searsare actuated 1 l and released from thecorresponding hammers 4:, l, to permit the firing of the respective barrels; The frame of the gun extends rearwardly forming the upper andunder plates 5 and 6 to which the gun stock is secured, the latter of saidplates also supporting the trigger mechanism. The numeral 7 designates the trigger whose forward end is pivotedto the block 8. This trigger plays through an alined slot in the lower plate 6, the downwardly projectin portion being formed into a finger grip an d abovethe plate 6 the trigger is widened forming'a comparatively wide release late 9" and this part of the trigger is exten ed rearwardly forming a finger-like extension 10 which plays in the trigger slot in the plate 6. A flexible U- shaped member is provided whose lowerarm 11 rests upon the upper surface of the plate 6 and has an oblong slot 12 therein and fitted closely against the under side of the plate 6 is a slide 13 which has a rib that projects up through a slot provided in the plate'6 and projects into the slot 12 and. a pin 14: passes "through said rib and its ends have hearings in saidlu'gs on arm lland the slide 13 has afsection thereof roughened as at 16 whereby it may be moved back and forth in its slot so as to adjust said U shaped memberwith the result hereinafter explained. The other arm 17 of the flexible U-shaped member ex tends over the release plate 9 of the trigger 7 and has the laterally projecting selecting fingers 18,18, extending in opposite direc- 1310118 and arranged n staggered relation.

This arm is formedof flexiblematerial and its free end normally extends over the release plate 9, said plate declining forwardly slightly from said arm as shown in Fig, 3. Secured to and upstanding from the plate 6 a is thepost 19 whose upper end is formed into the stops 20-.and 21 which are curved over,

their free ends pointing downwardly and said stops being spaced apart. The arm 17 has an. upwardly extending finger 22 provided to engage against one of said stops to prevent the-firing of the second barrel after the first barrel has been fired, until the trigger is released and again pulled. When the gun is not cockedthe finger 22 will be alined in position behind-its correspondingstop,

Fcharge,

said member being automatically released from the stop-upon release of the trigger, to permit the further movement of the trigger whereby the common sear-actuating means is brought into engagement with,and actuates, the other sear. a

trigger formed into a common sear-actuating a flexible selective sear-actuating into actuating position relative to said sears alternatively, locking members one fixed relative to the scars and the other carried by and movable with the selective means said last mentioned member being actuated by one of the searswh'en the corresponding hammer is in cocked position,

into engaging p0sit1o1iwith the other lockmember and locking the trigger against ing further movement after the first discharge,

Gopies of this patent'may be obtained for tively, a pair of stops,

when the trigger is pulled,

said movable locking member automatically disengaging from the fixed locking member upon release of the trigger to permit the further movement of the trigger whereby the common sear-actuating means is brought into engagement with and actuates' the other sear.

5. A trigger mechanism for double barrel guns including hammer controlling sears, a trigger formed into a common sear-actuating means, a flexible selective sear-actuating means capable of adjustment to actuate said sears alternatively, a pair of stops, a locking member carried by said selective means 7 and normally out of engaging position with said stops, said selective means being arranged to be flexed by one of the scars when thecorresponding hammer is in cocked position to bring said member into engaging position with the corresponding stop wherey y the'triggeris locked against further movement after the first discharge, said member being automatically released from said stop upon release of the trigger to permit a further 'movement of the trigger whereby the common sear-actuating means is brought into engagement with and actu ates the other sear.

6. A device of the character described including hammer controlling sears, a trigger formed into a common sear-actuating means, a flexible selective sear actuatmg means,

means for adjusting the selective means into operative connection with said sears alternaa locking member carried by said selective means and rovided to engage with said stops'alternatively accordingly as said selective means is adjusted into operative connection with one or the other ofsaid sears, sald member'being normally out of'operative connection with its corresponding stopand the selective means being arranged to be influenced by one of the scars when the corresponding hammeris in cocked position to bring said member into position to be engaged with thecorresponding stop whereby the trigger is locked against further movement after the first discharge, said member being automatically released from the stop upon release of the trigger to permit the 'further movement of the trigger whereby the common sear-actuating means is brought into engagement with and actuates the other sear.
